Do not remove the actuator heads from the valve body of the unit during normal operation or
maintenance. This may cause the changeover operation to malfunction.
CAUTION
Do not flush the system through the unit as this will cause debris to build up inside the pipework,
coil and valves.

Maintenance
Three Month Checks
Filters
The Filters are fitted primarily to stop the build-up of dirt and dust on fans, motors and coils that could be difficult to
clean. Dirty components would have a significant effect on the performance and life of the unit. The unit must not be
operated without filters. The filters require cleaning by vacuuming on both faces. The service interval referred to above
is for average air conditions. In a dirty environment filters will need more frequent cleaning or replacement.
Personal protective equipment (PPE), cordoned-off areas, vacuuming regimes and sealed refuse sacks to remove and
contain dust and particles that could become airborne may be required. Because of the potential hazard, dirty filters
need to be disposed of in an environmentally friendly manner in accordance with national and local regulations.
Contractors carrying out this work should ideally be registered under BS EN ISO 14001: Environmental Management
Systems (19).
Six Month Checks
Fan Impeller
Once the hinged fan assembly is lowered down it should be carefully cleaned by brushing and vacuuming. The fan
can be spun by hand to check if the impeller is in balance and is not rubbing or touching the fan housing. If an impeller
is tight to turn or stops spinning much sooner than other identical fans there may be a problem with the motor/fan
bearings.
Water Control Valves
Water control valves and valve actuators should be inspected for damage and signs of wear.
Check for leakage of water from valves and fittings.
Condensate Drip Tray and Pump
The condensate drip tray should be periodically flushed with clean water. To prevent issues caused by legionella
bacteria the drip tray should be cleaned with appropriate biocide.
Electrical Connections
Electrical wiring should be inspected for damage including evidence of burning or overheating. Electrical connections
should be examined and re-terminated if necessary.
12 Month Checks
Controls
The controls need to be checked for correct function including operation of the deadband between heating and cooling
modes.
Chassis
The Artus chassis should be inspected for damage and repaired if necessary. Exposed decorative casings should be
cleaned using warm water and a mild detergent. Abrasive cleaning materials should not be used. For cased units
ensure that all fixed panels, access panels, grilles and covers are secure and fixings and fasteners are tight to protect
against electrical and mechanical hazards. Ensure cables do not get trapped during any installation or maintenance
work.
Coil
Coil surfaces should be cleaned using a vacuum cleaner, drawing air through the heat exchanger in the opposite
direction to the normal air flow. Adjacent ceiling tiles may require moving for access. Coil faces, fins, pipe headers,
return bends and sheet metal end plates should be inspected for any damage, corrosion or leaks. These should be
repaired as necessary. The coil block should be vented to remove any air and damaged areas of fins should be combed
out straight.
Filter Replacement
The filters should be replaced after 12 months operation to ensure efficient unit operation. Three filters are fitted to
the unit and are required to be changed at the same time. The filters required to be changed are supplied in a kit from
Airedale. The kit comprises of two short and one long filter.
